Line an 8x8 or 9x9-inch baking pan with parchment paper and set it aside.
In a large saucepan set over medium heat, combine the brown sugar, honey, butter, and coconut oil. Cook for 1-2 minutes, or until the butter and melted.
½ cup brown sugar, ⅓ cup honey, 4 tablespoons unsalted butter, 4 tablespoons coconut oil
Add the peanut butter and whisk to combine— the mixture will thicken slightly.
½ cup creamy peanut butter
Once the peanut butter is combined, add the oats and ½ cup of peanuts. Stir to combine.
2 cups old-fashioned oats, ¾ cup peanuts
Transfer the granola to the baking dish and sprinkle over the remaining ¼ cup of peanuts.
Press the mixture into the pan, making sure to pack it tightly— you don’t want your granola bars to fall apart! Be careful, the mixture will be hot!
Transfer the bars to the fridge to chill for at least 2 hours.
Once the bars have cooled, combine the chocolate and remaining two tablespoons of coconut oil in a small bowl. Microwave until melted, stirring every 30 seconds.
1 cup dark chocolate chips
Slice the bars and drizzle the chocolate over them. Sprinkle with flaky salt, if desired. Transfer the bars to the fridge to set for at least 30 minutes.
